With the expansion of the application range of industrial displays, it can be seen in various public scenes. So, when choosing an industrial display, what kind of touch method should be considered first? Knowing the difference between the touch methods of industrial displays, users can choose products with better cost performance. And the commonly used touch methods for the touch methods of industrial display products on the market are generally capacitive screens and resistive screens. What is the difference between the two? How should users choose according to different usage needs and scenarios? Check it out with Flat Panel Display Factory!
First, the difference between capacitive screen and resistive screen
1. Power consumption
Industrial display capacitive screens are more expensive than resistive screens.
Capacitive screens are more expensive. Capacitive screens from different manufacturers are about 10% to 50% more expensive than resistive screens, and resistive screens are cheaper.
3. The feasibility of multi-touch
Capacitive Touch Screen Monitor's multi-touch can be achieved, depending on the implementation method and the software used, which has been achieved at present. The multi-touch of the resistive screen cannot be realized.
4. Visual effect
The visual effect of the capacitive screen and the resistive screen is very good indoors, but the visual effect is obviously different outdoors, especially under the sunlight. Capacitive screens work better, but resistive screens have poor visibility due to the extra screen layer reflecting the sun.
5. Environmental adaptability
Capacitive screens operate at temperatures between 0°C and 35°C and require a humidity of at least 5%. There is no specific value for the operating temperature of the resistance screen, but it has been confirmed that the resistance screen can work normally at a temperature of -15°C to 45°C, and the resistance screen has no requirements for humidity.
6. Touch sensitivity
Capacitive screens use current sensing of the human body, so any non-conductive materials such as nails, gloves, etc. cannot be recognized by the capacitive sensing system under the screen, but resistive screens work by pressure sensing. Yes, stylus is supported.
The capacitive screen needs to be touched with a finger, which is easy to leave stains on the screen, but because the outermost layer is a glass layer, it is easy to clean. The resistive screen supports operations such as stylus and nails, so it is not easy to soil the screen.
Second, different application scenarios correspond to different touch methods
1. If the Industrial Monitor only uses basic functions, a resistive screen should be used because the cost of the resistive screen is lower;
2. If the industrial display needs a longer standby time, you should choose a resistive screen, because the capacitive screen consumes more power than the resistive screen;
3. If the industrial display needs to use the multi-touch function, you should choose a capacitive screen, because the resistive screen cannot currently support this function;
4. If the industrial display requires a stylus, you should choose a resistive screen, because the capacitive screen works because the capacitive screen does not support the stylus;
5. If the industrial display will often impact it during use, you should choose a resistive screen, because the capacitive screen is fragile under impact;
6. If the industrial display is often used in the sun, you should choose a capacitive screen, because the resistive screen reflects the use of sunlight to affect the use.
That's it for the selection of industrial display touch methods. In general, when choosing industrial display products, you should mainly understand the advantages and disadvantages of capacitive touch and resistive touch methods, and find your needs to find the right product.
